Product Description




    20A Viewstar PWM Solar Charger Controller Solar Panel Battery PV System+ Remote

    Description of  PWM 20A

    ViewStar series solar controller is our new generation controller for off-grid solar system, such as street light, solar home system or small power station etc. The controller uses PWM (Pulse Width Modulation) technology which increases charge acceptance of your battery and extends its lifetime. PWM technology can also recover some lost battery capacity. This solar charge controller adopts the most advanced digital technique, displays on the LCD and operates fully automatically. LCD display can show various charging parameters e.g. voltage and current for the solar panel and battery.   

    Features of  PWM 20A: 

    • Adopt graphics dot-matrix LCD screen and HMI (human-machine interface) with 4 buttons, integrated menu displaying and operation
    • 32 bit MCU with high speed
    • 12 bit A/D high-precision sampling to ensure accuracy
    • Excellent EMC design
    • High efficient Series PWM charging
    • Use MOSFET as electronic switch
    • Widely used, automatically recognize day/night
    • Humanized design of browser interface, undertake every operating conveniently
    • Full control parameters setting and modification, diversified load control mode
    • Gel, Sealed and Flooded battery type option
    • Adopt temperature compensation, correction algorithm for charging and discharging parameters automatically

    Electronic Protections of PWM 20A:

    • Overheating
    • Over discharging
    • Over charging
